ANDREIV VIOKEY, OF QUINCY, ILLINOIS.

BALlNG-PRESS.

$PECIPICATION forming part of Letters Patent No. 366,547, dated July 12, 1887.

Serial No.208f2l. (Nomodch) To all whom it may concern:

Be it known that I, ANDREW \YrcKEY, of Quincy, in the county of Adams and Stateof lllinois, have invented certain Improvements in Baling-Presses, of which the following is a is delivered at the opposite end, the body be ing divided in the course of its formation into lengths or sections suitable for bales by boards introduced at proper intervals.

The aim of my invention is to permit the more convenient introduction of the charge and to secure a more effective compression of the hay; and to this end it consists in providing the receiving end of the trunk, sometimes termed the feed-chamber, with inwardly and outwardly movable side walls combined with operating mechanism by which they are caused to move outward during the introduction ofthe successive charges of loose hay, in order to afford an increased space for their admission, and then urged inward previous to or during the advance of the plunger.

My invention is susceptible of embodiment in various forms which will be apparent to the skilled mechanic after an examination of the accompanying drawings and the following description; but I have represented in the drawings a particular construction which appears to be the most serviceable under ordinary conditions. Inasmuch as the prcss may be in other respects of ordinary construction, I have illustrated inthe accompanying draw ings only those portions which are directly associated with my invention.

In the accompanying drawings, Figure 1 represents avertical cross-section through the receiving end or feed-chamber of the press 011 the line a: 00 of Fig. 2. Fig.2 is a longitudinal horizontal section on the line 3 y of Fig. 1. Fig. 3 is a longitudinal vertical section on the line .2 z of the preceding figure.

Referring to the drawings, A represents the frame of the press, which may be of any ordinary or appropriate construction; B, the re ceiving end of the horizontal trunk or chamber, commonly known as the feed-chamber; B,the pressure-chamber or trunk,open at both ends, into and through which the material is delivered by the plungerfrom the feed-chamber; O, the feed'opening, through which the hay is introduced into the top of the chamber; and D, the horizontal reciprocating plunger or heater, which advances periodically beneath and beyond the feed-opening for the purpose of addingthe successive charges to the'mass of hay and of gradually advancing the mass through the delivery end of the trunk in the ordinary manner. Ordinarily the side walls a of the receiving-chamber B are stationary. Under my improved construction they are movable, so that they may be separated horizontally, to afford an increased space between them for the admission of the hay, and then moved inward in line with the walls of the pressureehamber, so that the material may be delivered between them by the plunger into the pressure-chamber or trunk beyond. It will be perceived that the movement of the walls inward to positions flush with the walls of the pressure-chamber is necessary in order to permit the delivery of the charge. If the feed chamber were permitted to remain of greater width than the pressure chamber or trunk, the charge projecting laterally beyond the mouth of the feed-chamber would lodge firmly against its end. At its upper end each of these walls is connected by links I) to arms 0 on a horizontal rock-shaft, (I, mounted in fixed bearings e on the outside of the main frame. At its lower edge each of the walls is connected to two toggle links or joints, f, which are connected by upright rods or bars gto the arms of the rock-shaft above. These bars 9 are connected by links h to crank-arms i, fixed on opposite sidesofahorizontalshaft,j,lying athwart the main frame and mounted in bearings secured to its under side. Centrally upon this shaft there is fixed an arm, 7-3, the upper end of which stands normally in the path of the plunger D, while its lower end is pivoted to a sliding rod, Z, encircled by a spiral spring, m,

which tends to urge the arm in the direction indicated by the arrow.

When the plunger is retracted to permit the introduction of a charge of hay, it releases the arm 76, whereupon the spring at acts to turn the rock-shaft in such manner that its arms z efi'ect the deflection of the toggle-joints f and the rotation of the rock-shaft b, and the consequent retraetion or separation of the walls a. When, however, the plunger advances, it encounters the arm k, and, turning the same, acts through theintermediatepartstoforcethewalls a inward to their operative positions, thus compressing the hay laterally between them previous to the advance of the plunger. Thus it is that the receiving-chamber is expanded laterally for the reception of each charge, and then reduced or contracted automatically as the plunger advances to'carry the charge forward.

The essence of the-invention resides in the movability of the walls of the feed-chamber in a press of the class now under consideration, requiring the delivery of the charge from the v feed-chamber into the trunk or chamber beyond, and the combination of automatic operating mechanism therewith; and it will be manifest to the skilled mechanic that this operating mechanism may be variously constructed and that it maybe actuated either by the plunger, as shown, or in any other appropriate manner.

W'hile the best results are attained by arranging both walls of the receiving-chamber to retreat, as described, it will of course be understood that either wall may be left stationary, as usual.

I am aware that a cotton-press having a vertical chamber to receive the cotton and a screw driven plunger which enters the receiving end of the chamber to compress the cotton therein has been provided with automatic means for moving one of the side walls inward during the advance of the plunger, in order to effect the compression of the bale bot-h laterally and longitudinally, and I do not therefore claim, broadly, a compressing-chamber having side walls movable inward and outward.

My invention has .relerence to a class of presses opcratingin a manner widely different from the cotton-press above referred to. In my press the movable walls are appli'ed,not to the compressing-chamber,but to a feed-chamber open atits side and from which theplunger is never wholly withdrawn. My feed-chamber with its movable walls is combined with a distinct compressing-chamber or trunk, and the sole purpose of the movable walls is to reduce the feed chamber containing the loose 6o hay to a size corresponding to that of the pressure-chamber beyond, so thatthe hay may be delivered from the first chamberto the second. I

Having thus described my invention,what I claim is 1. In a continuous baling-press of the type pressure-chamber, and mechanism, substantially as described, acting to move the walls 7 of the feed-chamber outward beyond the walls of the pressure-chamberduring the retreat of .the plunger, and to move'them inward in line with the walls of the pressure-chamber during the advance of the plunger, whereby the feed-chamber is enlarged to receive the charge of loose material, and then reduced to a size correspondingwith the pressure-chamber, in order that the charge may be delivered to the latter.

2. In a continuous baling-pres's, the combination of the trunk or pressure-chamber open at its ends, the feed-chamber 13, having movable side walls, a, and a top opening, 0, a reciprocating plunger, D, arranged to traverse the feed-chamber, the lever 70, mounted in the path of and actuated by the plunger, and the toggle-joints and their connections between the lever is and the movable walls a, substantially as described, whercby'the advancing plunger is caused to force the two walls inward flush with the walls of the pressure-- chamber. w

3. In a continual baling-press, the combination of the pressure-chamber or trunk open at its ends, the receiving-chamber B, provided with a top opening and with the inwardlymovable side wal1s,a, the rock-shafts applied to the frame, the toggle-j oints connecting said shafts with the movable walls a, the transverserockshaftj, provided with crank-arms connected to the toggle mechanism, the lever 70, mounted in the path of the plunger, and the spring m,acting upon the lever, said parts constructed and arranged for joint operation, substantially as described.

In testimony. whereof I hereunto set my hand, this 17th day of June, 1886, in the presence of two attesting witnesses.
